RSS Fetcher Posted October 15, 2017 Share Posted October 15, 2017 <p>First - the image that started it all...</p><p> </p><p> </p><p> </p><p> presented by kind permission of the artist. The barge in the lock is the afore-mentioned 'Unity' and, as can be seen, is a 'wide barge'. She spent her working life plying the 'K&A' between Reading and Bristol carrying carbouys of acid...</p><p> </p><p> So on with construction. As previous blogs and other entries have mentioned, I am a firm believer in Knauff 'Floormate'* - sold as an underfloor insulation sheet about 250mm wide, 2.5m long and 75mm thick. Fortunately my supplier (Hampshire Insulation')* use it for purposes other than that for which it was designed and have a hot-wire cutter capable of cutting it down to (as a minimum) 5mm thick (if you're prepared to pay for the wastage!). The material itself is a 'high density urethane foam', completely stable, able to be easily cut with a craft knife, razor saw or (when 'her in doors' isn't looking) a breadknife! Obviously it does NOT like impact adhesives (except 'Limonene-based' ones) and PVA has an extended drying time if layering. However 'Gorilla Glue'* works a treat!</p><p> </p><p> For this project I used an offcut of a 30mm-thick board (it is only 600x240mm after all!), marked out the upper pound and lock as one unit, cut it out and dropped it by about 4mm, re-attaching it with the afore-said 'Gorrilla Glue' The lower pound was treated slightly differently in that it was cut from another offcut (hence the different colour) at 15mm thickness. When the upper pound/lock was set, the 'lower pound' was marked out and removed, then the new insert glued into place.</p><p> </p><p> </p><p> </p><p> The last view shows the end-view with the different water- and land levels clearly displayed. The prototype had a 'fall of over 2m so the differing thicknesses work well.</p><p> </p><p> </p><p> </p><p> Also on view is the first length of 'easitrack' - one & a bit more to go!</p><p> </p><p> When set, the board will be set into 6mm ply walls - this will take the 'hangers-on' like the lighting unit and fiddleyard cassettes.</p><p> </p><p> * the usual declaration - my only connection is as a thoroughly satisfied customer!</p><p> </p><p> Regards</p><p> </p><p> Ian</p><div id='attach_wrap' class='rounded clearfix'> <h4>Attached thumbnail(s)</h4> <ul> <li class=''> <a class='resized_img' rel='lightbox[20003]' id='ipb-attach-url-913299-0-81329800-1508085424' href="http://www.rmweb.co.uk/community/uploads/monthly_10_2017/blogentry-3469-0-38449200-1508083716.jpg"title="001 - Sharing The Load.jpg - Size: 42.71KB, Downloads: 0"><img src="http://www.rmweb.co.uk/community/uploads/monthly_10_2017/blogentry-3469-0-38449200-1508083716.jpg" id='ipb-attach-img-913299-0-81329800-1508085424' style='width:450;height:299' class='attach' width="450" height="299" alt="Attached Image" /></a> </li> <li class=''> <a class='resized_img' rel='lightbox[20003]' id='ipb-attach-url-913300-0-82277000-1508085424' href="http://www.rmweb.co.uk/community/uploads/monthly_10_2017/blogentry-3469-0-93694500-1508083733.jpg"title="002 - The 'board'.jpg - Size: 34.2KB, Downloads: 0"><img src="http://www.rmweb.co.uk/community/uploads/monthly_10_2017/blogentry-3469-0-93694500-1508083733_thumb.jpg" id='ipb-attach-img-913300-0-82277000-1508085424' style='width:800;height:220' class='attach' width="800" height="220" alt="Attached Image" /></a> </li> <li class=''> <a class='resized_img' rel='lightbox[20003]' id='ipb-attach-url-913301-0-82282200-1508085424' href="http://www.rmweb.co.uk/community/uploads/monthly_10_2017/blogentry-3469-0-67491300-1508083752.jpg"title="003 - Board end.jpg - Size: 45.88KB, Downloads: 0"><img src="http://www.rmweb.co.uk/community/uploads/monthly_10_2017/blogentry-3469-0-67491300-1508083752_thumb.jpg" id='ipb-attach-img-913301-0-82282200-1508085424' style='width:800;height:272' class='attach' width="800" height="272" alt="Attached Image" /></a> </li> </ul> </div> View the full article Link to post Share on other sites More sharing options...
